Austria Country Code +43
Austria uses country code +43 with an open national numbering plan. Area codes and subscriber numbers have variable lengths, so Austrian phone numbers can look quite different from one city or village to another – but they almost always follow the pattern (0A…) XXXXX domestically and +43 A… XXXXX internationally.
The capital Vienna uses the short area code 1, allowing longer subscriber numbers for businesses and government. Other major cities – Graz (316), Linz (732), Salzburg (662), Innsbruck (512) – use longer codes. Mobile numbers typically start with 6xx (e.g. 650, 660, 676, 699) and are widely used for both personal and business communication across Austria’s alpine regions and industrial hubs.
Austria at a glance for callers
Where you’ll see +43 in practice
Country code +43 appears on everything from Viennese banks and insurance groups to engineering firms in Upper Austria and tourism businesses in Tyrol and Salzburg. Typical use cases include:
- Manufacturing, automotive and machinery companies in Vienna, Graz, Linz and Steyr sourcing components and services across the EU.
- Hotels, ski resorts and travel operators in the Alps sharing +43 contact numbers for international guests.
- Logistics, freight and rail operators coordinating shipments along central European corridors.
If you see +43 1 …, that’s usually Vienna. Codes like 316, 512, 662, 732 point to Graz, Innsbruck, Salzburg and Linz, while mobile numbers generally start with 6xx (e.g. 650, 660, 664, 676, 680, 690, 699).
Language & communication style
- German is the official language; the Austrian variety (“Österreichisches Deutsch”) has its own accent and vocabulary.
- English is widely used in business, universities and tourism, especially in major cities.
- Email plus a direct landline or mobile number is standard on Austrian business cards and websites.
- WhatsApp, Signal and other messaging apps are common, but many organisations still prefer email or phone for formal communication.
For first contact, a short email plus a clearly formatted +43 phone number works well. Use German for government offices and smaller local businesses unless you know they are comfortable with English.
Austria phone number structure (+43)
Austria has an open numbering plan under country code +43. There is no single fixed length: area codes (national destination codes) can be 1 to 4 digits, subscriber numbers as short as 3 digits in small towns or much longer in big cities. Including the area code, national numbers typically range from 5 to 13 digits (excluding +43).
Geographic (landline) patterns
Domestic: 0 + area code + subscriber
- Area code (Vorwahl): 1–4 digits, often written with leading 0 inside Austria (e.g. 01 for Vienna, 0316 for Graz).
- Subscriber number: variable length; larger cities get shorter area codes and longer subscriber numbers.
- Example – Vienna: local 01 512 3456 → international +43 1 512 3456.
- Example – Graz: local 0316 123456 → +43 316 123456.
For parsing and validation, it’s usually enough to check that the full national number (without +43) is between 5 and 13 digits, then verify that the leading block matches an allocated geographic or mobile prefix.

The numbering plan is regulated by the Austrian Regulatory Authority for Broadcasting and Telecommunications (RTR) and conforms to ITU-T E.164.
Common landline area codes (examples)
| Local code (0A…) | City / region | Example international |
|---|---|---|
| 01 | Vienna | +43 1 512 3456 |
| 0316 | Graz | +43 316 123456 |
| 0662 | Salzburg | +43 662 876543 |
| 0512 | Innsbruck | +43 512 345678 |
| 0732 | Linz | +43 732 901234 |
Area codes are grouped by regions: Vienna (1), eastern Austria (2x…), southern (3x…), northern (4x…), western (5x… and 6x…), with additional finer-grained codes for smaller towns and districts.
Mobile prefixes & operators
Austrian mobile numbers usually start with 06… in local format. The next two digits indicate the original operator, though number portability means subscribers can switch carriers and keep their numbers.
| Prefix (0X…) | Typical operator / use | Example mobile |
|---|---|---|
| 0650, 0651… | Magenta / alternative operators (examples) | +43 650 1234567 |
| 0660, 0664… | A1 Telekom Austria & partners | +43 664 9876543 |
| 0676, 0677… | Magenta, virtual operators | +43 676 2345678 |
| 0680–0689, 0699… | Telemachus / other mobile & data services | +43 699 7654321 |
In E.164 format, mobiles are best stored as +43 6XXXXXXXX, stripping the leading 0 and leaving the remaining 9 or 10 digits as-is.
How to dial phone numbers in Austria
To call Austria you combine your international prefix, the country code +43, and the national number without its leading 0. Inside Austria, you keep the 0 and dial the full area code plus subscriber.
From abroad → Austrian landline
- Dial your country’s international prefix (e.g. 011 from the US/Canada, 00 from most of Europe).
- Dial 43 for Austria.
- Dial the area code without the domestic 0 (e.g. 1, 316, 662, 512, 732).
- Dial the subscriber number exactly as written (no extra zeros).
Example: calling a Vienna number 01 512 3456 from the US → 011 43 1 512 3456 or +43 1 512 3456.
From abroad → Austrian mobile
- Start with your international prefix (011, 00, +, etc.).
- Add 43 (Austria).
- Take the mobile number as printed (e.g. 0664 987 6543) and remove the initial 0 → 664 987 6543.
- Dial +43 664 987 6543.
There is no additional “9” or national access digit for mobiles – you simply drop the 0 and attach +43.
Dialing inside Austria
- Local landline (same area): subscriber number only, or full 0 + area code + number (both typically work).
- Landline from another area: 0 + area code + subscriber (e.g. 0316 123456).
- Mobile calls: always dial the full number with leading 0 (e.g. 0664 987 6543).
- International from Austria: 00 + country code + number (mobile users can replace 00 with “+”).
For customer databases, it’s safest to store all numbers in international format +43… and keep a separate “display” format for invoices and letters.
Practical dialing tips
- Austrian numbers can be deceptively short (small villages) or long (large corporates in Vienna). Don’t assume a fixed 10-digit length.
- Some service numbers (0800 freephone, 0900 premium-rate) may not be reachable from abroad.
- When validating web form input, allow for variable lengths but enforce that internationalised numbers look like +43[1–9]… with a reasonable total length limit (e.g. 5–13 digits after +43).
Time in Austria (CET / CEST)
Austria follows Central European Time (CET, UTC+1) in winter and Central European Summer Time (CEST, UTC+2) in summer. Daylight saving time usually runs from the last Sunday in March to the last Sunday in October.
Time zone overview
| Zone | Abbrev. | UTC offset | When used |
|---|---|---|---|
| Central European Time | CET | UTC+1 | Late Oct → late Mar |
| Central European Summer Time | CEST | UTC+2 | Late Mar → late Oct |
In the IANA time zone database, Austria uses the zone Europe/Vienna.
Typical time differences
- London: typically 1 hour behind Vienna (0 in winter if UK is on GMT, 1 hour in summer).
- New York: usually 6 hours behind (e.g. 09:00 in Vienna ≈ 03:00 in New York in winter).
- Tokyo: normally 8 hours ahead of Vienna in winter, 7 hours ahead in summer.
- Sydney: about 9–10 hours ahead depending on both regions’ DST schedules.
For business communication, Austria’s working day overlaps well with most of Europe and parts of the Middle East and Africa; overlap with North America is mainly in Austria’s late afternoon.
Emergency numbers in Austria
Key emergency short codes
Austria uses the European emergency number 112 alongside national 1xx codes for specific services:
- European emergency number: 112
- Fire brigade: 122
- Police: 133
- Ambulance / rescue: 144
- Mountain rescue: 140
- Medical on-call / emergency doctor: 141
In most situations, visitors can simply dial 112 from any mobile or fixed phone and be routed to the appropriate local service.
Additional hotlines
• Child helpline: 147 (“Rat auf Draht”).
• Crisis hotline / Samaritans-style services: various 14x / regional numbers.
• Poison control: specialist centres reachable via regular geographic numbers in Vienna.
For consular assistance, foreign nationals should contact their embassy in Vienna or the relevant consulate. Emergency contact numbers are published on each mission’s website.

FAQ: Austria country code & dialing
Why do Austrian phone numbers have different lengths? +
Austria still uses an open plan, where area codes and subscriber numbers have variable lengths. Large cities like Vienna get shorter area codes and longer subscriber numbers; small villages share longer area codes with shorter subscriber numbers. This is why some Austrian numbers look unusually short or long compared with fixed 10-digit systems.
How many digits are in an Austrian phone number? +
There is no single standard length. Including the area code (without +43), Austrian national numbers usually range from 5 to 13 digits, with most business and mobile numbers falling in the 9–10 digit range. When stored in E.164 format, you’ll see +43 followed by 5–13 digits.
Do I keep the leading 0 when I add +43? +
No. Just like many European countries, the initial 0 in 0X… is a trunk prefix for domestic calls and is not used when dialing from abroad. You should:
- Remove the 0, keep the rest of the area or mobile code.
- Prepend +43 → e.g. 01 512 3456 → +43 1 512 3456; 0664 987 6543 → +43 664 987 6543.
For CRMs and messaging apps, always store numbers as +43….
Is +43 a “safe” country code or used a lot for scams? +
Most +43 calls are normal business, tourism or family calls. As everywhere, there are also spam and fraud attempts (e.g. fake parcel or bank messages), but +43 itself is not inherently “riskier” than other European codes.
- Be cautious with unexpected calls asking for payments, login codes or remote access.
- Verify claims via official websites or known contact numbers, not the number that called you.
- Businesses dealing with Austria should use call-back from known +43 numbers and avoid sharing sensitive data over the phone.
Can I call Austrian freephone (0800) or premium (0900) numbers from abroad? +
In general, no. Non-geographic numbers like 0800 (freephone), 0810/0820 (shared cost) and 0900 (premium rate) are designed for callers inside Austria and may not be reachable from other countries or via all carriers.
If you need to reach an Austrian organisation from overseas, ask for a standard geographic number (+43 1…, +43 316…, etc.) or a mobile (+43 6…).
